fc::tuple<> Struct Template Reference

#include <tuple.hpp>

Detailed Description

template<BOOST_PP_ENUM_PARAMS_WITH_A_DEFAULT(9, typename A, void)>
struct fc::tuple<>
Provides a fast-compiling tuple that doesn't use fancy meta-programming
techniques.  It is limited to 4 parameters which is sufficient for most 
methods argument lists which is the primary use case for this tuple. Methods
that require more than 4 parameters are probably better served by defining
a struct.

The members of the tuple are easily visited with a simple visitor functor 
of the form:
@code
struct visitor {
  template<typename MemberType>
  void operator()( MemberType& m );

  template<typename MemberType>
  void operator()( const MemberType& m );
};
@endcode

template<typename A=void, typename B=void,typename C=void, typename D=void>> struct tuple { tuple(){} enum size_enum { size = 4 };

template<typename AA, typename BB, typename CC, typename DD> tuple( AA&& aa, BB&& bb, CC&& cc, DD&& dd ) :a( fc::forward<AA>(aa) ), b( fc::forward<BB>(bb) ), c( fc::forward<CC>(cc) ), d( fc::forward<DD>(dd) ) {}

template<typename V> void visit( V&& v ) { v(a); v(b); v(c); v(d); } template<typename V> void visit( V&& v )const { v(a); v(b); v(c); v(d); }

A a; B b; C c; D d; };
